properly a plied, and that the cover may be easily t en o and put on.

The invention will be claimed at the end hereof but will be first described in connection with the accompanying drawings forming part hereof and in which- Figure 1, is a top or plan view of a jar having a, cover em odying features of the invention. Fig 2, is a vlew of the under side of the cover. Fig. 3, is a sectional view of a jar having'a cover embodying features of the invention, and Fig. 4, is a view, partly in section, taken at right angles to the section of Fig. 3.

In the drawings 1, is a cover having integral flanges 2 and 3, projecting from one of its faces and generally parallel with each other so as to form between them a groove 4. In this groove 4, is arranged the sealing compound 5. The sealing compound is usually a substance or material which softens, when heated, and sets upon cooling. As shown the inner flange '2, is somewhat deeper than the outer flange 3, which is a matter of some convenience. The rim 6, of the jar is received by the groove 4, in such a way that the sealing compound 5, fills the space between the two and thus forms a perfectly tight joint. The flange 3, may coperate with the bead 7, of the jar as a stop and as a means for retaining the sealing compound. While the ribs 8, on\ the jar tend to stiften it as does also the bead 7 still the flanges 2 and 3, with the scaling compound and the rigidity of the cover 1, and its umtary or one-piece flanges crosswise parts of the 2 and il. ail`ord a strong and reliable support for the top of the jar.

As shown in the drawings the cover is intended for use with a jar sub-divided by partitions 9, and so the jar wall proper is received b v the marginal part ot' the groove 4, while the partitions are received bv the groove l. (lf course if the jar does not have partitions. the crosswise parts of the groove 4, are omitted and the marginal part of the. groove 4. re tained. Since the flanges 2 and 3. are intcgral with the rover l, the coronas a. whole ma) be made quite light. Furthermore si'ncc each of the tlauges is integral with the cover, the position of the flanges in respect to each other is fixed and unchangeable. The tact that the llang'es are integral with the cover provides for ease. in assembling the scaling compound and the other parts.

The cover 1. is supported by the plate structure l0. and not b v the top rim of the jar wall. In consequence of this the top rim of the jar wall may not be crowded into or caused to fill the space in the bottom ot the groove i. which is provided for the sealing compound. so that this space occuied by the sealing compound is maintained. and the sealing compound is not forced out.

It will be obvious to those skilled in the art that modifications may be madein di tails of construction and arrangement, hence. the invention is not limited in regard to such matters nor further than the prior state of the art and the following claims may require. i

lVhat I claim is:

l. In a storage battery the combination of a cover provided with integral flanges projecting from one face thereof and constitntinY between them a groove having space or the reception of scaling' compound. sealing compound in said space, a. jar having the top of its wall arranged in said groove, and a plate structure holding and positioning the cover in respect to the top rim of the wall to maintain said sealing s ace. o l

2. n a storage battery the combination ico ai www pmvded with ntegm flanges the Qm'er in rspcct tn the, top rim of the ug funn one. fuffa thereof and wn f' 'wall i@ maintain said Sealing space. mtxwon twm a grauw having BRUCE FORD iii@ reception of seaing Compound, Y Cumpmmd in Said .wmf-Q, :l jm hav- I Yitneses: i if@ of; its wa c; :"'nzgvd in Said Emu: L LQNUAKER,
